Inverter Type machine vs. Normal welding machine for MIG/TIG/ARC

Hey everyone I have to ask what's the difference between an inverter type welding machine and a non-inverter type.
What I have noticed is that inverter type welding machine draws less input current but other than that I don't know a thing. I have an inverter type MIG welding machine and tried it in aluminum. Oh man the result was a disaster. There was weld spatter everywhere on the workpiece and melted the workpiece right thru. My workpiece is an aluminum sheet 2-3mm thick BTW.

Can anyone suggest how I can solve this problem? Is it with the machine or the setting of the machine? If its with the setting what will be the best setting for such an application? Thanks!

What machine are you using and what are your settings and the wire you are using and type of wire.

Actually I used a machine that we OEM from a manufacturer in China. I dont have any experience yet on using MIG machine so basically I know scratch about it.
But some details I was able to gather. they were using .9mm Aluminum MIG wire. The wire feed rate was quite slow... does this affect the welding performance of the machine?

actually it's the MACHINE...you need one made in AMERICA
seriously...you haven't told us "scratch" either!!!
My advise would be to fiddle around with all the knobs untill it welds correctly Also read the manual. Search this website...it has all the answers you seek.
If you are a cheap chinese welding machine importer then shame on you for coming here for answers IMO. If not then my mistake and sorry.

Yes, actually we are an importer of Chinese products and am not ashamed of it. We're already 25 years into the distribution of welding machines. But only last year that we started into the electronic type welding machines. Well I'm just trying to learn from others so next time we can improve our machine to perform to an acceptable quality compared to american welding machines.
I do believe that miller and nihonweld machines will be top class, but you see in the Philippines not a lot of people can afford to buy such expensive machines.
I'm very sorry if my posts lack info or hard to understand, that's why I'm a newbie welder.
